This day hike in Portugal’s Madeira archipelago might be relatively short compared to others on this list, but it will definitely put your endurance to the test. Linking two of the island’s highest peaks, the route has its share of steep ascents and narrow ridges. The path is clearly defined, as it sees a lot of foot traffic, making it manageable for solo hikers. Although you’re likely to come across other walkers, the dramatic scenery makes you feel like you’re on a wild adventure far from civilization.
5. Camino de Santiago, Spain
For those seeking solo adventures, few trails are better suited than the Camino de Santiago, a network of historic pilgrimage routes stretching across Spain and beyond. The infrastructure makes it super easy to navigate without any stress. The paths are well-marked, and there are plenty of cafes and albergues (cheap hostels designed with pilgrimage-seekers in mind) along the way. The steady flow of fellow pilgrims means you can decide when you want to be alone and when you want to build social connections with others.
